I tried it and created a full RAG application very easily. I followed the examples in the online documentation and it was really a piece of cake. My previous implementation of RAG (without Datapizza) used direct libraries such as OpenAI, Sentence Transformers, etc. Instead, I find it very useful to have a “framework” where you already have everything. In the past, I played around with Langchain, but I find it really immense, as complete and large as it is complex and distracting.
